Title: Read/write head for article identification system
Inventor: MORIKAWA KAZUNORI
IPC: G06K7/08
Filed: 1990-09-07
Abstract: PURPOSE:To prevent malfunction due to an interference noise by increasing the reception level of a read/write head. CONSTITUTION:The pulse of the resonance frequency of a data carrier is counted by a first counter 13, and when a count value arrives at a prescribed value (N), a signal is supplied to a first pulse transmission circuit 4, and positive and negative pulses are outputted. Also, when (n) pulses less than N are counted by a second counter 22, the pulses are sent in the same direction as that of the pulse sent from a second pulse transmission circuit 24. By performing such operation, it is possible to increase the level at a time when a second pulse is sent although a reception pulse is attenuated gradually, and to accurately count the number of pulses.

Title: Extension unit and power control method therefor
Inventor: ONO SHINICHI
IPC: G06F1/18
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To obtain an extension unit connected with a master unit through a connector while being supported only at the connector part and operable with power supply from other than the master unit in which the extension unit is protected against breakdown or firing by blocking power supply under a state where the extension unit is not connected with the master unit. SOLUTION: Under a state where an extension unit is connected with a master unit 5 through a connector 4, a signal monitor circuit 6 detects a signal being obtained from the master unit 5 upon connection and sustains an interrupting circuit 2 in conducting state. Consequently, power is supplied to a main circuit 3 and the extension unit is operated normally. When extension unit is disconnected from the master unit 5 due to some cause, the interrupting circuit 2 is brought into interrupting state because the signal monitor circuit 6 can not detect a signal being obtained from the master unit 5 upon connection. Since power is not supplied to a main circuit 3, operation of the extension unit is interrupted and the extension unit is protected surely against breakdown or tiring due to continuous power supply.
